Abstract
Provided are nonwoven polymeric fiber webs using an improved curable composition. Such curable composition comprises an aldehyde or ketone and an amine salt of an inorganic acid. The composition when applied to polymeric fibers is cured to form a water-insoluble polymer binder which exhibits good adhesion and thermodimensional stability.
